hauled l-aterallypf a combine-during :the opera- 1 tion thereof, so that-the grain threshed-may be directly deposited into the cg'rainawagon.

-Another object ofthis-inventionlis to provide a hit'ch 'of the character mentioned above which allows the wagon to bevery' easily attached detached' from the d-rawbarr a 1 stilllanother object of this invention is to whichimay be swungupwardly to theside of the combine when not in use.

'Still another object ofthis invention is torprovide' a fihitch for acombinewhich may zbe sadjust'e'd for attachmentithereto, thus rnakingzthe sanre hitch usable with 'difler'ently proportioned frames indifferent makes of combinesu V iAnother object of this invention is tolprovide improved means for limitingthe downward pivotal movement of the drawbar, =-'and:other means to tacilitate the securing of a tongue :i'Of the wagon to be pulled at different positions -onithe drawb'ar.

Another "obj ect which iis ancillary to all i the 1 and '15 provide a'd-rawba'r hitch assembly-for a combine foregoing objects, :is to provide-means :by the use of which the necessity of moving the coin-.

,bine away from normal operation in vorderto aunload grain is obviated. i

And a last object to :be'mentionedispecifically is ita -provide a device of this general character which -is relatively inexpensive andipracticable to manufacture, which is safe, 'simple and "convenientto use under vary conditions, and which 7 will give generally eificient and durable "service.

Withthese objects definitely in Jview,xthis;:in-

Y '2 portions of' this I invention and the grain being: shown in 1 front elevation Figure3 is a three-dimensional View of the tongue guide, a portion of the -drawbar being' shown 1 in phantom lines, and the pla'te having bayonet slots therein positioned below the tongue guide, the figure being designed to show primarily f the U-shaped structure of the tongu eguide =portion which actually contacts the} tongue Figure 4 is a sideelevational view of a front p rtion of'a ton'gue constructed -ac cordinlg'fto this I invention, together with a tongue guide, a tongue and the plate having the bayonet aper tures'I-and Figure 51sa horizontal sectional view taken 'on' the line -"5 -5 in Figure 1, the ifigure being "do signedl'to u'show'the construction or a stop plate incorporated with the hinge structure on the draw-bar, whereby-"the 'drawloar is limited-in its downward pivotal movement, the i hinged endpf f the'iirawb'ar being shown in twopositions.

Similar characters of reference designatesimilar elements and portions, or identical *elements and"portions, throughout the specification throughout the several views of *the drawings.

. Referring i now 1 to the drawings in detail, =the' environment wherewith this invention: is adapted I to be -used includes a tractor which will have-adrawbar [:0 :-.-to"whi=ch;is secured. the forward end l2- 0f thei'frameof thecombine, generally indicated by qthe anumeral I14. [This frame 1 will.-: ordinarily include substantially horizontal .forwardlyaextending members It: and I8 which may varylzin .sizeaanol angular disposition-in different makes of combines. The environment WlII'JQJSO include:aigigrain wagonlfl:having atongue 22,-;ra

clevis :24 :and a kingbolt with an enlarged head zfi.

This invention :contemplates provision .of ray:

drawbarassembly'rn including what will there ferred:to-asthe drawbar-BiJ-terminating at the inneraend -1 -i'I1 a barrel 32 disposed transversely thereof .andsadapted to receive a .hinge1 pin 44f, and the drawbar Ml has lintegrally secured thereto a! brace 36 L terminating Eat? itsinner end ina siinilar barrel 38 to receive a similar pin 34, andl-final-lyoanotherbrace lfi terminally secured a to intermediate .portions of the brace -.36 and,

the drawbar '30,. this brace 40. havin rigidly: se

cured thereto the end portions 142' of substan- 1 tia'l'ly s-shaped stop members 44.

The drawbar attachment assembly 46 includes a bar 48 having U-shaped brackets 50 secured to wagon 3 the ends thereof and apertured to receive the hinge pin 34 while straddling the barrels 32 and I8, and on the opposite side of the bar 48 two attachinent plates 52 and 54 of different lengths comprise the means for securing the bar 48 to the combine frame member [6. It will be noted that the plates 52 and 54 are secured to the horizontal frame member 16 by U-bolts the upper ends of which are illustrated at 5B, and the plates 52 and 54 are each longitudinally sldtted-,iiasjat.='-58.* A pair of coa'cting attachment plates 80 and'82 are similarly secured by U-bolts to the horizontal pairs of bolts 84 may be inserted through the slots in each of the pairs of plates for securement I thereof against relative motion, thus firm1y,se-,

curing the bar 48 to the frame of the combine.

The ends 66 of the S-shaped stop members 44 are adapted to engage the bar 48 when the drawbar 30 is in substantially horizontal position. This construction is shown very clearly in Figure 5 it may here be noted that when the drawbar is not in use, the same may be tilted upwardly and moved over center to rest upon the side ofthecombine.

A tongue guide, generally indicated bythe numeral 68, is comprised of a sleeve adapted to slide longitudinally upon the outer end of the drawbar 3B. Rigidly secured to this sleeve and on the upper side thereof is a U-shaped bracket 12, and on the underside of this sleeve is secured a plate 14 having a pair of bayonetslots I6 adjacent either end thereof. -A pin 18 extends from the bight portion of the U-shaped member-12 downwardly and diametrically through'the sleeve 10 and through the plate 14, and the drawbar 30 is provided with a plurality of regularly spaced vertically disposed holes 80, when the drawbar is" in horizontal position, to receive an intermediate portionof the pin 18, thus making itpossible-to adjust the tongue guide longitudinallyof the drawbar 30.

The tongue 22 is of special design to the extent that a chain 82 is secured to the forward end thereof by any suitable means such as a loopedstrap 84 and a ring 86, while another chain 88 is secured tothe kingbolt 26 within the clevis 24.

The forward end of the chain 88 isinserted;

through one of the bayonet slots 16 whilethe rearwardly disposed end of theother chain 82- is inserted through the other of the bayonet slots.

The operation of this invention will be'clearly understood from the foregoing description'of the'" mechanical details thereof, taken in connection with the above recitation of the: objects sought to be achieved by this invention. In recapitulation,

it may be added that the tongue 22-will be placed in the U-shaped member I I2, whereafter the chains 82 and 88 are secured in tight relation in= the bayonet slots '16. VVhen' th wagon is loaded, the tongue 22 is released from the device by a reversal of the steps indicated immediately above.

vious that the same may be tilted upwardly against the side of the combine.

It'is clear that all the objects sought to be fullynoted that minor variations may be made When the drawbar isnot in use, itis obdrawbanand said tongue guide being disposed 4 ited only as determined by a proper interpretation of the terms used in the subjoined claims.

Having described the invention, what is claimed as new is:

1. A hitch mounted on the frame of a combine whereby a wagon, having a tongue with a clevis and a kingbolt, may be hitched laterally of the combine, comprising a drawbar extending from one side of said frame, a tongue guide secured on said' drawbar, a plate having bayonet slots therein carried on said drawbaradjacent said tongue I guide, chains each having one end secured to combine frame member l8 and these plates 60 and 52 are also longitudinally slotted, so. that longitudinally spaced apart portions of said tongue-intermediate portions of said chains being securable in said bayonet slots while an adjacent portion'of said tongue is in said tongue guide, to

, prevent relative movement between said tongue and said drawbar, stop plates incorporated with said hinge connection to limit the downward movement of said drawbar, one of said chains having an end thereof secured to the forward end of said tongue, and the other of said chains h'aving an end thereof securable to the kingbolt with- 1 in said clevis:
